The energy released when an ion is hydrated i.e. accepts water molecules is known as hydration energy. Smaller ion in size accepts a large number of water molecules so its hydration energy is more and they greater will be its hydrated … Webof atomic radius, ionic radii increase on descending a group. Ionic size (for the same ion) also increases with increasing coordination number, and an ion in a high-spin state will be larger than the same ion in a low-spin state. In general, ionic radius decreases with increasing positive charge and increases with increasing negative charge. short ankara gown with sneakers
